Audio analyzer errors in Safari

I am using the example here:
https://developer.playcanvas.com/en/tutorials/music-visualizer/

but in Safari i get this error:

this.analyser.getFloatTimeDomainData is not a function. (In ‘this.analyser.getFloatTimeDomainData(this.timeData)’, ‘this.analyser.getFloatTimeDomainData’ is undefined)

Are there any workaround for Safari?

Thank you,

Alex
